--- Comment #1 from sandra at gcc dot gnu.org ---
I see this in tm.texi on mainline head:

<snip>
@deftypefn {Target Hook} reg_class_t TARGET_PREFERRED_OUTPUT_RELOAD_CLASS (rtx
@
var{x}, reg_class_t @var{rclass})
Like @code{TARGET_PREFERRED_RELOAD_CLASS}, but for output reloads instead of
input reloads.

The default version of this hook always returns value of @code{rclass}
argument.

You can also use @code{TARGET_PREFERRED_OUTPUT_RELOAD_CLASS} to discourage
reload from using some alternatives, like @code{TARGET_PREFERRED_RELOAD_CLASS}.
@end deftypefn
</snip>

I think there is nothing to do here any more.
